First World problem: There are four Starbucks locations around my house, and I never know which one to go to because the coffee-deprived slog to each is the same half-mile length. If you get the sense, like I do, that Starbucks is everywhere, it’s because there are 13,279 of them in the U.S. alone, and they’re so crammed into highly trafficked areas that sometimes, as Lewis Black famously bemoaned, there’s a Starbucks directly across the street from a Starbucks. You can recognize a city by its streets or population patterns. Can you recognize it by its Starbucks locations?

Let’s find out. The above quiz shows all of the Starbucks locations within the city boundaries of 20 domestic or foreign cities, and for each you must name the city depicted from four choices. Note the number of locations and the shape of their pattern; watch for peripheral clusters that may indicate airports; and if you haven’t had your caffeine yet, get it now—this will tease your brain more than the Slate Friday News Quiz. At last, all you world travelers will have more to show for it than your city-specific Starbucks mugs.
